[QUOTE="FordTechOne, post: 1823150, member: 35543"] In the first video it sounds like an exhaust manifold leak, but in the 2nd video it sounds more like a failed lash adjuster or broken valve spring. Does the truck run rough or misfire? Broken valve spring(s) will typically cause those issues, but it depends where the spring broke. Either way I wouldn’t continue to drive it, if a spring it broken you risk dropping a valve, which will cause serious engine damage. [/QUOTE]
